movie. I prefer to read the book before watching the movie and I do this on my own time frame- the movie came out over a year ago, I think. The book is entertaining whether you have children or not. The main character's hectic pace and time commitment to her career/job can be similar to a nurse's lifestyle, especially those of us who work extra shifts or second jobs.
Allison Pearson wrote another book, I Think I Love You. The main character is in teenage-love with singer David Cassidy. I read that book first and did not find it as entertaining.
